Helpful for Model Matching:
| Product action | Hydraulic section single acting, pneumatic section double acting; pneumatic pressure intensifies hydraulic release output and spring returns the hydraulic piston. Integrated spindle air-blow function and low oil-cup level sensor location are shown. No universal spindle fit is implied. |
| Code combinations | 35T only 63×13; 45T63×13 or 63×15; 60T only 70×15. Code labels mean 3.5/4.5/6.0T class, not 35/45/60 tonnes. Bore is hydraulic-cylinder diameter; stroke is release travel in mm. |
| Pressure and force distinction | Specification operating air 0.5–0.8MPa; operation note requests stable 0.6–0.8MPa. At 0.6MPa specification/dimension table gives 3.5/4.5/5.7T for 35T/45T/60T. The theoretical curve gives 3.8/4.6/5.7T at 0.6MPa. Keep these source differences; neither code class nor curve is an unconditional release-force guarantee. |
| Air and environment | Filtered air 40 μm or finer; −5 to 60°C; proof pressure 1.0MPa is separate. Main air port PT3/8; air-blow connection is separate in drawing. Source warns water and insufficient/unstable air can prevent normal operation. |
| Electrical code | A AC220V; B DC24V; C AC110V; E AC24V; F DC12V. D is not published. Blank vertical DIN plug; L lead. Blank no microswitch; 2 two microswitches. Source references 4M310 valve, but no blanket replacement/electrical wiring interchangeability is established. |
| Position and switch setup | Limit switches signal end positions into machine control. Source describes adjust at limit then back off 0.5–1.5 mm and resecure; PLC delay relay is part of required machine sequencing. Confirm actual switch wiring and tool-change sequence with spindle drawing; the pinout depends on the supplied switch. |
| Mounting and travel | For vertical spindle, bracket-fixed above spindle. Mount perpendicular to spindle axis, permitted deviation≤0.05 mm/100 mm. Release travel set to actual spindle need: too short prevents release; too long loads/damages spindle/tool drawbar. Machine clearance depends on the installed spindle geometry as well as cylinder stroke. |
| Oil and service | ISO VG32 hydraulic oil specified; different brands/types must not be mixed. Source describes frequent initial cycling to bleed air and fill until level reaches the line. Oil-level and lubrication/service inputs require actual assembly confirmation; do not treat a generic oil substitute as approved. |
| Operational boundary | Source prohibits spindle tool-release operation without the proper toolholder present and requires matching toolholder/drawbar and travel setup. Air-blow and oil controls are part of the installed system. A code match does not establish machine safety or installed release compatibility. |
